Check out an article a guy named Bolda wrote in this blog June 22, 2013. Symptoms are described and shown to be similar to those here in new growth. Tissue analysis shows high K, low slightly low Ca, Mg, but most notably, Fe - 380 compared to 336 in the present case. Is there a linkage between high K and insufficient Fe?

Hi Thom, boy you sure do read this closely. Let me look at that blog post here shortly and compare it to what we have here. It could be informative - thanks!

Hi Thom,  
I have had some time to review this. You are indeed right, in both the 6/22/2013 post and this one K is quite a bit higher in the new leaves than the older ones. However, in reviewing one of my plant nutrition books (the very accessible "Plant Nutrition and Soil Fertility Manual" by J. Benton Jones, Jr.), K actually increases the mobility and solubility of Fe, which sounds like it would be the opposite of what we see here.  
So, I would still stand on N outrunning the ability of the plant to move Fe to these new leaves, rather than an inhibition brought about by high K.  
Really appreciate the input and close reading!

Are these canes grown for future artificial chill or a normal fruiting cycle?

Hi Dominic,  
Normal fruiting cycle.

I wonder if the results are the same if the sample was sap petiole..would this result will be different ? In a substrate production, we have a 7/24 control..see the Salts in the edge but what the mottle yellowing mean in term of mineral efficiency...see it a lot in heavy soil, and some var. are more affected than others
